Multi-Scale Prediction and Simulation of Localization Banding in Granular Media
Abstract
Shear bands are a critical factor in the response of granular materials, such as soils, rocks, and concrete. The objective of this research is to develop methods for accurately predicting the onset and propagation of deformation bands in granular media under extreme environments by developing an efficient multiscale simulation framework. The goal is to bridge continuum scale methods with the existing discrete methods to obtain an accurate multiscale model that can be used to predict and model shear band inception and propagation in granular media. Fundamental understanding of granular mechanics under shear banding will pave the way to tackling more challenging phenomena such as projectile penetration and blasting.
